Office Action

§103 §112 §DP
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Terminal Disclaimer Applicant's election without traverse of group (A1) and (B2) in the reply filed on 7/7/2025 is acknowledged. The terminal disclaimer filed on 11/04/2025 disclaiming the terminal portion of any patent granted on this application which would extend beyond the expiration date of Application 17/545,110 has been reviewed and is accepted. The terminal disclaimer has been recorded. Election/Restrictions Applicant's election without traverse of group (A1) and (B2) in the reply filed on 7/7/2025 is acknowledged. Claims 10 and 16 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected group. With respect to the instant claim 15, a search of the prior art did not show the elected species. As none of the claims were specifically drawn to applicant's elected species in combination with the limitations of one of claim 15 in independent form, no claims have been indicated as allowable. However, claims written in independent form which require all the limitations of claim 15 as well as being limited to the elected species along with any dependent claims which require all the limitations of claim 15 as well as being limited to the elected species would be allowable. Claim 15 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims as well as being limited to the elected species. This objection to the claims is only with respect to Applicant’s elected species. It is noted that the potential allowability of claim 15 has not be determined with respect to species beyond Applicant's elected species, i.e. potential examinable species that could found once the search is expanded beyond Applicant's elected species. Response to Amendment The amendment of 11/04/2025 has been entered. Disposition of claims: Claims 1-20 are pending. Claims 10 and 16 have been withdrawn. Claims 1, 9, 11, 14, and 17-20 have been amended. The amendments of claim 14 has overcome the rejection of claim 14 under 35 U.S.C. 112(b) set forth in the last Office Action. The rejection has been withdrawn. The amendments of claims 1, 9, 11, 14, and 17-20 have overcome the rejections of claims 1-9, 11-14, and 17-20 under 35 U.S.C. 103 as being unpatentable over Zeng et al. (US 2018/0006247 A1, hereafter Zeng) in view of Acharya et al. (“Effect of Selenium Substitution on Intersystem Crossing in π-Conjugated Donor−Acceptor−Donor Chromophores: The LUMO Matters the Most”, J. Phys. Chem. Letts 2016, vol. 7, page 693-697, hereafter Acharya) set forth in the last Office Action. The rejections has been withdrawn. The Terminal Disclaimer approved on 11/04/2025 obviates the provisional nonstatutory double patenting rejections of claims 1-9, 11-15, and 17-20 set forth in the last Office Action. The rejections have been withdrawn. Response to Arguments Applicant’s arguments see page 79-82 of the reply filed 11/04/2025 regarding the rejections of claims 1-9, 11-14, and 17-20 under 35 U.S.C. 103 as being unpatentable over Zeng/Acharya set forth in the Office Action of 08/06/2025 have been fully considered and are persuasive. The rejections have been withdrawn. Claim Objections Claim 9 is objected to because of the following informalities: In claim 9, Applicant claims duplicated formula structures of the ligands LAi’-47 and LAi’-48. It is suggested to delete one of the duplicates. Appropriate correction is required. Claim Rejections - 35 USC § 112 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claims 9 and 11-14 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claim 9, Applicant claims the ligand LA which can be LAi’-m or LAi-m’, wherein m is an integer from 1 to 85 and m’ is an integer 86 to 116. However, for some m and m’, the corresponding structural formulas have been deleted. For example, there is no structural formula wherein m is 6, 7, and 8. It is unclear whether Applicant claims the structural formulas wherein m is selected from an integer from 1 to 85 and m’ is selected from an integer 86 to 116, or whether Applicant claims the undeleted structural formulas. For the purpose of prosecution, the Examiner interprets the limitation to mean that Applicant claims the undeleted ligands. Additionally, there are two structural formulas corresponding to LAi’-45 and LAi’-46 (page 13 last two rows). It is unclear which structure is claimed as LAi’-45 and which structure is claimed as LAi’-46. For the purpose of prosecution, the Examiner interprets the limitation to mean that Applicant claims both structures as LAi’-45 and LAi’-46. Regarding claims 11-14, claims 11-14 are rejected due to the dependency from claim 9. Claims 9 and 11-14 are rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Regarding claim 9, claim 9 recites “The compound of claim 1, wherein the ligand LA is selected …” and claims specific structural formulas of the ligands LA. However, some of the ligand is not encompassed by the ligand LA of claim 1 because some of the ligands do not comprise deuterium. For example, ligand LA1’-1 having structure of PNG media_image1.png 97 107 media_image1.png Greyscale , wherein RE is R1 PNG media_image2.png 94 76 media_image2.png Greyscale and G is G1 PNG media_image3.png 119 70 media_image3.png Greyscale does not comprise any deuterium atom. The ligand LA in the compound of claim 1 is required to comprise at least one deuterium atom. Currently claim 9 is dependent from claim 1. Therefore, claim 9 fails to include all the limitations of the claims upon which they depend. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Regarding claims 11-14, claims 11-14 are rejected due to the dependency from claim 9. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 1-8 and 17-19 are rejected under 35 U.S.C. 103 as being unpatentable over Li et al. (US 2016/0133861 A1, hereafter Li) in view of Kim et al. (US 2008/0194853 A1, hereafter Kim). Regarding claims 1-8, 17, and 19, Li discloses a compound represented by one of Formulas I to X and used for an organic light emitting device ([0006]-[0015]). Li exemplifies a compound ([0160], the fourth compound on page 41, hereafter Compound p95-1). PNG media_image4.png 386 475 media_image4.png Greyscale In the Compound p95-1, the substituent corresponding to Rb of Formula VII is not deuterium; however, Li does teach that the substituent Rb can be deuterium ([0014]). Kim discloses Ir complex compound used for an organic light emitting device (abstract). Kim teaches that deuterium has grater atomic mass, lower zero point energy, lower vibration energy, and lower van der Waals force, and lower intermolecular collision by vibration such that the substitution of hydrogen of an Ir complex with deuterium provides improved luminescence efficiency, luminance, current efficiency, power efficiency, and thermal stability ([0021]-[0022]). Kim exemplifies an Ir compound comprising phenyl pyridine ligand, wherein the phenyl ring of the ligand is substituted by deuterium ([0037]). At the time the invention was effectively filed, it would have been obvious to one of ordinary skill in the art to have modified the Compound p95-1 by substituting the hydrogen atoms at the position corresponding to Rb with deuterium, as taught by Li and Kim. The motivation of doing so would have been to provide greater atomic mass, lower zero point energy, lower vibration energy, and lower van der Waals force, and lower intermolecular collision by vibration such that the Ir complex provides improved luminescence efficiency, luminance, current efficiency, power efficiency, and thermal stability, based on the teaching of Kim. Furthermore, the modification would have been a combination of prior art elements according to known material to achieve predictable results. See MPEP 2143(I)(A). The substitution of the substituents from H to D at the position Rb in Formula VII of Li would have been one known element for another known element and would have led to predictable results. See MPEP 2143(I)(B). PNG media_image5.png 403 592 media_image5.png Greyscale The modification provides Compound of Li as modified by Kim, meeting all the limitations of claims 1-8 and 19. Li in view of Kim does not disclose a specific organic light emitting device comprising the Compound of Li as modified by Kim; however, Li does teach that the compound of Li can be used as the emitter of an organic light emitting device ([0006]).

The modification provides Organic light emitting device of Li as modified by Kim comprising an anode, an emissive layer (Compound of Li as modified by Kim as an emitter, and a host), and a cathode, meeting all the limitations of claim 17. Regarding claims 1-6 and 18, the Compound of Li as modified by Kim reads on all the features of claim 1 as outlined above. The compound does not have a 5-membered ring at the position corresponding to the ring L1 of Formula VII of Li; however, Li does teach that the ring L1 can be a pyrazole ring ([0116]). Li exemplifies a compound wherein the ring corresponding to the ring L1 of Formula VII of Li is pyrazole ([0160], see examples including at least the 4th compound on page 41). At the time the invention was effectively filed, it would have been obvious to one of ordinary skill in the art to have modified the Compound of Li as modified by Kim by substituting the pyridine ring at the position corresponding to the ring L1 of Formula VII of Li with pyrazole, as taught by Li and Kim. The modification would have been a combination of prior art elements according to known material to achieve predictable results. See MPEP 2143(I)(A). The substitution of pyridine with pyrazole at the position corresponding to the ring L1 of Formula VII of Li would have been one known element for another known element and would have led to predictable results. See MPEP 2143(I)(B). The modification provides Compound of Li as modified by Kim (2). PNG media_image6.png 442 554 media_image6.png Greyscale Claim 20 is rejected under 35 U.S.C. 103 as being unpatentable over Li et al. (US 2016/0133861 A1) in view of Kim et al. (US 2008/0194853 A1) as applied to claims 1-8 and 17-19 above, further in view of Pang et al. (“A full-color, low-power, wearable display for mobile applications”, SPIE, 03/29/2012, hereafter Pang). Regarding claim 20, the Organic light emitting device of Li as modified by Kim reads on all the features of claim 17 as outlined above. The device comprises an anode, an emissive layer (Compound of Li as modified by Kim as an emitter, and a host), and a cathode.

Kim discloses Ir complex compound used for an organic light emitting device (abstract). Kim teaches that deuterium has grater atomic mass, lower zero point energy, lower vibration energy, and lower van der Waals force, and lower intermolecular collision by vibration such that the substitution of hydrogen of an Ir complex with deuterium provides improved luminescence efficiency, luminance, current efficiency, power efficiency, and thermal stability ([0021]-[0022]).

At the time the invention was effectively filed, it would have been obvious to one of ordinary skill in the art to have modified the Compound p95-1 by substituting the hydrogen atom at position 3 of the pyridine ring of the phenyl pyridine ligand with deuterium, as taught by Li, Kim, and Zhang. The motivation of doing so would have been to provide greater atomic mass, lower zero point energy, lower vibration energy, and lower van der Waals force, and lower intermolecular collision by vibration such that the Ir complex provides improved luminescence efficiency, luminance, current efficiency, power efficiency, and thermal stability, based on the teaching of Kim, and to provide the organic light emitting device comprising the compound with prolong device lifetime, lower driving voltage, and higher power efficiency based on the teaching of Zhang.

Li in view of Kim and Zhang does not disclose a specific consumer produce comprising the Organic light emitting device of Li as modified by Kim and Zhang; however, Li does teach that the invention of Li can be used be for a consumer product (display or lighting devices in [0080]-[0081]). Zhang teaches an organic light emitting device can be incorporated in a television ([0042]). At the time the invention was effectively filed, it would have been obvious to one of ordinary skill in the art to have modified the Organic light emitting device of Li as modified by Kim by incorporating it into a television, as taught by Li and Zhang. The motivation of doing so would have been to provide a consumer product such as a television comprising an OLED device, based on the teaching of Zhang.

The only difference is that the dibenzoselenophene group is required to be benzoselenophene; however, Li does teach that the fluorescent luminophore group of F1 in the Formula VII can be a benzoselenophene group represented by PNG media_image12.png 87 137 media_image12.png Greyscale , wherein R1I and R2I can be each hydrogen ([0122]-[0126]). At the time the invention was effectively filed, it would have been obvious to one of ordinary skill in the art to have modified the Compound of Li as modified by Kim and Zhang by substituting the dibenzoselenophene group with a benzoselenophene group, as taught by Li. The modification would have been a combination of prior art elements according to known material to achieve predictable results. See MPEP 2143(I)(A). The substitution of the fluorescent luminophore groups in the compound of Li would have been one known element for another known element and would have led to predictable results. See MPEP 2143(I)(B). Regarding the bonding position in the selenophene ring, there are finite number of substitutable positions. The selection of the bonding position next to the selenium atom in the selenophene ring would have been one from a finite number of identified, predictable solutions, with a reasonable expectation of success. See MPEP 2143(I)(E). Additionally, the compound having bond next to the selenium atom is a position isomer of compound having bond at any other available ring carbon of the benzoselenophene group.
